PUZZLE.

Specification of Letters Patent.

Patented Aug. *7, 1917.

Application filed January 6, 1917. Serial No. 140,996.

To all whom it may concern:

Be it known that I, HENRY Gr. Fnezrnn, a citizen of the United States, residing at Grafton, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Puzzles, of which the following is a specification.

This invention relates to improved puzzles, and has for one of its objects to provide a puzzle formed from wire bentinto shape and including a plurality of loops, and a key member including a longitudinally directed slot, the loops. being so arranged that the slotted key member must be manipulated and moved in a certain predetermined order around and through the loops to enable it to be detached.

In the drawings illustrative of the pre ferred embodiment of the invention Figure 1 is a side elevation of the puzzle.

Fig. 2 is a plan of the same.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved puzzle is formed from wire in cooperating portions, one portion being swingingly coupled to the other portion. The main portion of the puzzle comprises a stock 10 having an eye 11 at one end to swingingly support a relatively large ring 12, the latter designed to prevent the key member from being removed in one direction from the stock.

At one end the stock 10 is extended into a relatively large loop 13 open at one end, as shown at 14 and with oppositely directed smaller open loops 15-16 intermediate the ends of the stock. The loop 13 is directed obliquely to the longitudinal axis of the stock, as illustrated in Fig. 2. A larger loop 17 is disposed substantiallyin parallel relation to the stock 10, the loop 17 having a relatively contracted entrance 18. The loops 1317 are connected by a plurality of bends 1920, as shown in Fig. 1. An other laterally directed loop 21 extends from the loop 17 at the side opposite to the bends 1920, the loop 21 being extended at one side and connected at 22 to the lateral loop 15 of the stock, the connecting portion between the loop 21 and the connection 22 being reversely bent into open loops 2324, as shown in Fig. 1. Pivoted at 25 to thelateral stock loop 16 is a member bent into a loop portion 26 and a straight portion 27, the loop 26 having a relatively contracted entrance 28 at its juncture with the straight portion 27.

At its terminals the portion 27 is formed into a relatively long loop 29 which swings upon the l0op13. The loop 29 forms a thumb and finger grip by which the device isheld during the first stages of the operation of removing the key member, the latter being represented as a whole at 31 and including a relatively long slotted portion 32 and a finger grip portion 33.

The eye or loop portion 32 of the key is engaged initially with the stock 10, as shown in Fig. 1, the length of the slot being less than the diameter of the ring 12 so that the key member cannot be detached by passing the same over the ring.

The puzzle is to remove the key member from the device without bending or distorting any of the parts.

Assuming that the parts are initially ar ranged as shown in Fig. 1, to remove the key member the swinging loop 26 is turned upwardly until the portion 30 between the portions 2627 passes through the open space 18 of the loop 17, the eye 2529 being so disposed that the portion 30 will pass through the portion 18 when this swinging movement is made. The operator then passes the free end of the portion 32 of the key over the loop 24 and thence over the oppositely disposed loops 1516 and passes the outer portion of the loop 32 into the loop 21 and passes the body portion of the loop 32 over the eye portion 25 and thence passes the body of the loop over the outside of the loop 26 and passes the body of the loop thence over the eye 25 and thence over the loop 13 and passes one side of the loop 32 into the loop 19. When thus disposed the key member may be turned until it is in parallel relation to the larger loop 17 and will pass readily off from the latter, and is thus released. The length of the loop 32 and the sizes of the other loops will permit the above described movements without cramping the parts, as the key can be turned to adapt it to the forms of the various loops and bends.

The device is simple in construction, can

be inexpensively manufactured and will afford amusement and instruction to persons attempting to solve the puzzle.

Having thus described the invention, what is claimed as new is- 1. A puzzle of the class described including a stock portion having a ring swinging therefrom at one end and an open loop at the other end and reversely directed lateral open loops intermediate the ends, another loop having a restricted inlet and connected to the open loop by a plurality of oppositely directed bends, a laterally directed loop extending from the last mentioned lateral loop and one of the intermediate lateral loops of the stock, a member swinging at one end from the other intermediate stock loop and with an elongated eye at the other end movably engaging the first mentioned loop, said swinging member includin an open loop and a straight section, and a key member including an elongated loop loosely engaging the stock initially and of less length than the diameter of the swinging ring.

2. A puzzle comprising a longitudinally directed stock and a plurality of loops connected to each other and to the stock, one of said loops having a contracted inlet, amember swinging relative to said stock and including a loop and a contracted portion, said contracted portion adapted to pass through the inlet to said loop, and a key member having an elongated loop and initially disposed thereby upon said stock.

3. A puzzle comprising a longitudinally directed stock having a ring at one end and a plurality of loops connected to each other and to the stock atthe other end, one of said loops having a contracted inlet, a member swinging relative to said stock and in-,

eluding a loop and a contracted portion, said contracted portion adapted to pass through the inlet to said loop, and a key member having an elongated loop of less length than the diameter of the ring, said key member disposed by its slot initially upon said stock.
